WITNESSES); I 5 ifif yww SIGN.

To all whom it may concern Be it known that 'I, Gmonoa E. Jamzmos,

acitizen of theUnited, States, and resident though the entire structureremains stationary and. the advertising matter remains unchanged andalways visible in its entirety.

My invention comprisesthe novel detailsof improvement that will be morefully hereinafter set forth and then pointed out in the claims.

. Reference is to be had to the accompanyingadrawings forming arthereof, wherein-.-

I igure 1 1s a front e evation of a sign embod mg m invention; Fi 2 is avertical sectlon, su stantially on t e plane of the line 2, 2 in Fi 4;Fig. 3 is a face view of the rear mem r or back round, the front memberbeing removed,san Fig. 4 is a horizontal section, substantially on theline 4, 4' in Fig. 1

In the drawings thenumeral 1 indicates a front member or board, shownrovided with a plurality of openings 2', w ich are shown in the form ofrelatively narrow elonated slots cut or otherwise formed in memer 1.Said member may be formed by cutting the openings 2 directl from asuitable sheet or suitably'built up card, or may be formed of slatssuitably connected together.

At 3 is a rear. member or board shown in solid form, located directlybehind the front member 1, to be seen through 0 enin s 2 of the latter,and spaced at a s'uita 1e distance from the front member 1. shown thefront member 1 and the rear member 2 are connected by suitable spacers5, and said mem'bers may be supported in any suitable manner, as bybraces 6 holding the front and rear members in a firm structure, U onthe front face of rear member 3 'a' suita is design is produced, such asby painting thereon stripes 7 or other suitable pattern, or such designmay be applied by pasting suitable paper or the like on the rear member,and the outer face of the front member, orthe front faces of the slats,may

invention is to provide and when 'the observer the .parts of the stripesor and In the form v be painted or otherwise produced in colorscontrasting to the colors of the stripes or design 7. Advertising orother matter may ,be placed on the outer face of the front member 1, andsuch matter may be painted on the front member or may be made inseparate parts, such'as of wood, metal or the like, and laid on theforward face of the front member, as indicated at 8.

A sign. produced in accordance with my Patented May 3, 1910.

invention may be located in "any suitable position, where a person willobserve the same while gassing the sign, as, for instance, along t eside of a railway track, on the side of a building, or in other suitableposition asses or is carrie past the sign and while ookin at the sameesign on the rear member 3 which are visible throu h the openings 2 ofthe front member 1, W111 appear to move while the advertising mat.

ter remains statmnary and always visible in its entirety. In otherwords, the device provides an apparently movin back ound for theadvertising matter, giving a p easing effect and one that will ,attractattention. It will thus be understood that while the parts of the siremain stationary relative to each other t e movement of the observerrelatively to the sign causes the apparent movement of parts of thesign, or an optical illusion, without requiringany movement of the 51 nor its parts. Hence the sign may be insta ed and aft without anyattention of construction shown and described, as the same ma be variedwithin the scope of the a pende claims without de arting from t a spiritof my invention, an while I have described my invention asa foradvertismg signs it wil V e understood that the same may be utilized forother analogous purposes; a

Having now described my invention what I claim is 1. A sign comprising amember havin a glurality of o enings, a permanently visl le esign u on te front face of said member inde en ent of said openings, and a rear memer maintained at a distance from the front member in fixed relation tothe same and provided with a design ada ted to be seen through saidopenings an arranged in such relation to the openings in the front getthe effect of a moving slgn is pro licable to use member as to causeapparent movement of the visiblep'arts of the rear design when anobserver passes the sign, the first named design remaining unchangedin-appearance at al times from any ang e of vislon.

2. A si 11 comprising a front member provided wit a lurality ofsimilarly disposed openings, a design superimposed upon the front ofsaid member and partially coverin said openings, and a rear membermaintaine at a d1stancefrom the front member in fixed relation tothesame and provided. with a suitable design adapted to be observed throughsaid 6 enin the rear design be ing so spaced rom t e front member astobe partially visible through the front openings at all angles of visionso as to cause apparent movement of the rear design beber in fixedrelation to the same and pro- Y vided on its forward face with a designhaving lines and spaces at an angle to the openings of the .front memberada ,ted to be seen through said openings, the mes on the rear memberbeing partially visible through the front openings and artially obscuredby the solid parts of the ront member.

4. A si 11 comprising a front member provided wit a plurality ofparallel openings and solid portions located at an angle to thehorizontal and provided on the front face with a permanently visibledesign independent of said 0 enings, a rear member located at a suitab edistance from the front member and provided with a design havingsubstantially parallel lines and" spaces located at an angle to theopenings and solid portions of the front member to cause the ap earanoeof undulating motion of the vislble parts of the rear design when anobserver passes'the sign all parts of the sign being maintained in fixedrelation to each other at all times.
